Seborrheic dermatitis is a medical inflammatory skin disorder affecting the scalp, face, and body.
Normally, seborrheic dermatitis begins with a flaky, itchy, scaly, and red skin.
It especially involves the sebaceous-gland-rich areas of skin.
In older children and adults, seborrheic dermatitis normally manifests as scalp scaling similar to dandruff or as mild to marked redness of the facial smile line fold.
It can happen with or without reddened skin.
